IMPROVEMENT IN VALVES FOR STEAMPIPES.

Speciilcation forming part of Letters Patent No. 146,073, dated December30, 1873 5 application filed June 7, 1873.

To all whom it may concern:

Be it known that I, JAMEs W. HonGEs, of the city and State of New York,have invented an Improvement in Valves for Steaming such valves, so thatthe passage of steam through the main valve can be regulated and theescape of air or water of condensation can take place through the secondcock, and both cocks occupy but little space and can easily be operated,simultaneously or otherwise.

I make use of a barrel and two couplingconnections, one above and theother below the seat of the main valve, which valve is operated by ascrew-stem, as usual. A diagonal partition isintroduced near the end ofthe barrel, and there is a second screw-valve introduced at the side toclose upon the valveseat that is made at one side of this partition, andthe pipe or opening is at or near the end of the barrel. By means of thesmall valve the escape of air may be allowed for, or water ofcondensation may be run away with regularity, the said small valve beingmore easily adjusted than the larger ones heretofore usually employed,and simplifying the connections and lessening the space usuallyoccupied.

In the drawing, Figure l is a vertical section of the cock complete, andFig. 2 is a partial transverse section.

The barrel a is made with the couplings or connections b and c for steamor other pipes,

and between' these pipes is the seat d for the v valve e, that is uponthe end of the screw-spinv dle f, that passes through the cap g andpacking, which are of usualcharacter. The partition his near thev end ofthe barrel a, and is formed with a seat, c', at one side of thepartition, and 7c is the valve and screw-stem, the latter passingthrough the cap l. These parts are much smaller `than those of the valvec, so as to be proportioned to the pipe lm., that passes away eitherfrom the side or end of the Y bination with the main valve c and connecltions b and c for the pipes,substantia1ly as and for the purposes setforth. Signed by me this 31st day of May, A. D. 1873.
